Abstract
A method of providing an efficient channel structure for a communication system that uses codes to define its communication channels. Available codes form a code space that is equally divided into M tiers based on load conditions; M is an integer equal to 1 or greater. Information is scheduled to be transmitted during a particular time slot and is assigned to a particular tier. The information is transmitted during the scheduled time slot using all of the codes of the assigned tier.
Claims13
A method of providing an efficient channel structure over which information is transmitted where the channel structure is used in a communication system that uses codes to define its communication channels, the method comprises the steps of:
- scheduling transmission of information for a particular time slot during which an entire available code space is used for the transmission;
- dividing the available code space into M tiers based on load conditions whereby each tier has a code space that is a portion of the available code space and M is an integer equal to 1 or greater;
- and
- transmitting the information during the scheduled time slot using the entire code space of a tier assigned to the user.
The method of claim where the load conditions are (a) number of codes available, (b) number of users available, and (c) a user application specific amount of information to be transmitted.
